Abstract A convenient synthetic approach to (1H-1,2,3-triazol-1-yl)acetic acid derivatives via the reaction of azidoacetamides with β-ketoesters and acetylacetone is proposed. Based on this strategy, 1,5-disubstituted 1,2,3-triazoles were prepared from available reagents under metal-free conditions. A one-pot protocol for the synthesis of (5-methyl-1H-1,2,3-triazol-1-yl)acetamides derived from N-substituted
摘要 提出了一种简便的合成方法,该方法通过叠氮乙酰胺与β-酮酸酯和乙酰丙酮的反应来合成(1 H -1,2,3-三唑-1-基)乙酸衍生物。基于该策略,在无金属条件下由可用试剂制备了1,5-二取代的1,2,3-三唑。开发了用于合成衍生自N-取代的氯乙酰胺的(5-甲基-1 H -1,2,3-三唑-1-基)乙酰胺的一锅方案。
